1
Practical Phonetics Consonants: place and manner of articulation Where and how sounds are made
2
Say ‘mmmm’ – where is the ‘m’ sound produced? It’s a bilabial consonant (this is the place of articulation) Pinch your nose – what happens? It stops: it’s a nasal (not an oral) consonant Put your fingers in your ears – what do you hear? The vibrations of the vocal cords: it’s a voiced consonant Thinking about sounds
3
Some places of articulation: bilabial consonants p pie b buy m mute w wood lips
4
Labiodental consonants f fine v vine upper teeth lower lip
5
Dental consonants θ thin ð this upper teeth tip of tongue
6
Alveolar consonants t tie d die s Sue z zoo n night l light alveolar ridge tip/blade of tongue
7
Post-alveolar / palato-alveolar consonants ʃ shoe, pressure Ʒ pleasure ʧ cheap ʤ jeep r rack
8
Palatal consonants j yes
9
Velar consonants velum back of tongue k curl g girl ŋ rang
10
Some manners of articulation: plosives (think explosion) or stops Bilabial: p bAlveolar: t dVelar: k g
11
Fricatives (think friction) Labiodental: f vAlveolar: s z Palato-alveolar or post-alveolar: ʃ Ʒ
12
Oral Nasal (Velum is lowered, allowing air to enter the nasal cavity)
13
Nasals Bilabial: mVelar: ŋ Alveolar: n
14
Other consonants Affricates (a combination of stop + fricative): ʧ = voiceless post-alveolar affricate ʤ = voiced post-alveolar affricate Approximant (articulators approach each other but do not touch): w r j Lateral (also called lateral approximant; air flows over sides of tongue): l

17
Classifying consonants Voiced or voiceless Place of articulation (Central or lateral) (Oral or nasal) Manner of articulation Example 1 : s (sing): -A voiceless, alveolar, (central), (oral) fricative -A voiceless, alveolar plosive/stop = ? /t/ What is /k/? - A voiceless, velar plosive/stop
